There are weird differences between Google and Alexa. For example you can ask Alexa to "check email" to have it check your assigned GMail account, tell you how many messages there are, read the subjects and then for each one Read full message, Skip, or Reply by voice. Google can't check email at all, even its own Gmail.
And the Alexa Skills allow other companies to add certain features more easily than Google does. For example the Tidal music streaming service is not supported by Google, but it is supported by an Alexa Skill.
